O'Donnell ran the offense in a walk-through practice on Wednesday and will be prepared to start Sunday against Tampa Bay if the Titans decide to rest Steve McNair (ankle/calf), The Sports Xchange reports.

O'Donnell would be a starter on many other clubs, yet he only got the chance to attempt five passes for Tennessee last season. Given McNair's durability, do not expect O'Donnell to get many opportunities this year either.
